# Isentropic flow relation between pressure and density

Calculate the Isentropic flow relation between pressure and density with our free online tool using the input parameters: Pressure, Density, Ratio

Isentropic flow in thermodynamics refers to a flow process where no heat enters or leaves the system, and there are no energy transformations due to friction or dissipative effects. The relationship between pressure and density in isentropic flow is given by the equation P / ρ^{γ}. You can use this online isentropic flow relation calculator to calculate this relationship based on the total conditions of physical force and solidity, which are considered constant throughout the process.

P / ρ^{γ} = P_{t} / ρ_{t}^{γ}

The variables used in the formula are:

`P / ργ`

`P`

= Pressure

`Pt`

= Total Pressure

`ρt`

= Total Density

`γ`

= Specific Heat Ratio
